RE: CFC - Changes to Target Size for Issue 631


I’ve thought about this more after the call today, and have moved my opinion “from strong reservations” to “cannot live with this.”

I think that this new target size minimum definition opens the door for unintended consequences, which could negatively impact the people we are trying to accommodate and protect under the guidelines.  A 44px by 1px target size minimum, would provide web content owners an excuse under our guidelines to render unusable touch targets to critical information they have to display by law, but don’t want to display conspicuously. I don’t want to ratify Success Criteria that empower content owners to do wrong by the disability community.  I fully understand that the intent of this change in target size minimum is to get content owners to start thinking about providing adequate pointer targets, but unfortunately, I believe the SC as amended will be abused.  Plus, we still don’t have any empirical evidence that backs up the claim that this target size minimum will actually make the difference for people with disabilities who want to use a mouse on desktop and/or touch input on mobile devices, instead of being forced to use a keyboard (or equivalent).
